Checkout the [demo](https://nuxy.github.io/webform-toolkit) for examples of use.

## Dependencies

- [Node.js](https://nodejs.org)

## Installation

Install the package into your project using [NPM](https://npmjs.com), or download the [sources](https://github.com/nuxy/webform-toolkit/archive/master.zip).

$ npm install webform-toolkit

## Usage

There are two ways you can use this package.  One is by including the JavaScript/CSS sources directly.  The other is by importing the module into your component.

### Script include

After you [build the distribution sources](#cli-options) the set-up is fairly simple..

```html
<script type="text/javascript" src="path/to/webform-toolkit.min.js"></script>
<link rel="stylesheet" href="path/to/webform-toolkit.min.css" media="all" />

### Module import

If your using a modern framework like [Aurelia](https://aurelia.io), [Angular](https://angular.io), [React](https://reactjs.org), or [Vue](https://vuejs.org)

```javascript
import WebFormToolkit from 'webform-toolkit';
import 'webform-toolkit/dist/webform-toolkit.css';

const webformToolkit = new WebformToolkit(container, settings, callback);
```

### HTML markup

```html
<div id="webform-toolkit"></div>
```

### Example

```javascript
const settings = {
  action: 'https://www.domain.com/handler',
  params: 'name1=value1&name2=value2',
  submit: false, // Override submit button creation.
  groups: [
    {
      legend: 'Login Form',
      fields: [
        {
          id:          'username',
          label:       'User Name',
          type:        'text',
          name:        'username',
          value:       null,
          maxlength:   15,
          filter:      '^\\w{0,15}$',
          description: null,
          placeholder: null,
          error:       'Supported characters: A-Z, 0-9 and underscore',
          required:    true
        },
        {
          id:          'password',
          label:       'Password',
          type:        'password',
          name:        'password',
          value:       null,
          maxlength:   15,
          filter:      '^(?!password)(.{0,15})$',
          description: null,
          placeholder: null,
          error:       'The password entered is not valid',
          required:    true
        }
      ]
    }
  ]
};

const container = document.getElementById('webform-toolkit');

const webformToolkit = new WebformToolkit(container, settings, callback);
```

| step        | Input number step ([range](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/range)) | false |
| filter      | Validate form input using REGEX                         | false    |
| description | Custom field description ([Supported text tokens](#supported-text-tokens)). | false |
| placeholder | Input field type placeholder text.                      | false    |
| error       | Custom error message (Required, if `filter` is defined) | false    |
| required    | Required field.                                         | false    |

## Supported text tokens

The following Markdown elements are supported in the `description` attribute:

| Token Type   | Example                  |
|--------------|--------------------------|
| Bold         | &ast;&ast;bold&ast;&ast; |
| Italic       | &ast;italic&ast;         |
| Link         | &lsqb;alt text&rsqb;&lpar;https://www.example.com&rpar; |

## Callback processing

When a callback function is defined a form object is returned. This allows you to define a custom AJAX handler based on the requirements of your application. The following function corresponds to the [example](#usage) provided above.

```javasctipt
function callback(form) {
  const xhr = new XMLHttpRequest();

xhr.addEventListener('load', function() {
    if (this.status == 200) {
      alert(response);
    }
  });

xhr.open('POST', form.getAttribute('action'));
  xhr.send(new FormData(form));
}
```

## Adding fields

I have added a method to dynamically create form fields that can be added to an existing webform. An optional callback has also been provided to for post-processing FORM and field elements. This makes it easy to show/hide fields using conditions and expressions.

```javascript
webformToolkit.create({
  id:          'new_field_id',
  label:       'New Field',
  type:        'text',
  name:        'new_field',
  value:       null,
  maxlength:   null,
  filter:      '^[a-zA-Z0-9_]{0,255}$',
  description: 'This is my new field',
  placeholder: null,
  error:       'Supported characters: A-Z, 0-9 and underscore',
  required:    true
},
function(form, elm) {
  form.appendChild(elm); // default: last in fieldset
});
```

## Best practices

Just because you are filtering form input on the client-side is NO EXCUSE to not do the same on the server-side.  Security is a two-way street, and BOTH ends should be protected.

## Developers

### CLI options

Run [ESLint](https://eslint.org) on project sources:

$ npm run lint

Transpile ES6 sources (using [Babel](https://babeljs.io)) and minify to a distribution:
